Akio Ootsuka, Champ/Oushi Black's voice actor recently posted a picture taken from a recent party for the Uchuu Sentai Kyuranger movie which has Minami Keisuke in it but was deleted immediately minutes after it was posted. Could this be a hint that we already have an actor for Phoenix Soldier?
As we all know, Minami Keisuke has already portrayed a role in a Super Sentai series and that was in the 6th episode of Enjin Sentai Go-onger where he played the roled of Seiji, Saki's love interest.

Let's wait for the confirmation of this exciting news in the upcoming issues of Terebi Kun and Terebi Magazine as the next issues will finally focus on the debut of Phoenix Soldier!
